Checked with the installer and where I purchased the speakers. I STAND CORRECTED they are in fact 2 OHMS. my bad I hope this clears things up. My apologies to all.
Well according to my spec sheet, it is the "sport muffler' and described as such on the Nismo sheet as well. So I am confused as why they would call it the same thing on the spec (sticker sheet and brochure sheet. In any event still sounds good.
